Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5557984-2 are identified based on the following critical parameters that must align for functional equivalency:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 50
• Number of Rows: 2
• Mounting Type: Through Hole
• Connector Style: Outer Shroud Contacts
• Contact Finish: Gold
• Category: D-Sub, D-Shaped Connectors

Allowable Variation Parameters:

• Termination Method: Press-Fit or Solder (both are through-hole termination technologies)
• Packaging: Bulk or Tray (does not affect functional performance)
• Flange Feature: Housing/Shell or Board Side (both support 4-40 mounting)
• Manufacturer: Different manufacturers permitted when all electrical and mechanical parameters align

The substitute part B57-050-221-202 from Mercury United Electronics, Inc. satisfies all mandatory matching parameters while differing only in termination method (Solder vs. Press-Fit) and packaging configuration (Tray vs. Bulk). This substitution is valid for applications where solder termination is acceptable as an alternative to press-fit assembly.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 5557984-2

The TE Connectivity AMP Connectors 5557984-2 is the specified component for applications requiring press-fit termination technology. This part maintains Active product status with established supply availability (1162 pieces in stock). The connector is RoHS Compliant and carries REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications.

Substitute Part: B57-050-221-202

The Mercury United Electronics B57-050-221-202 serves as a functional substitute when solder termination is acceptable within the application design. This part is ROHS3 Compliant and also carries REACH Unaffected status. Both parts maintain identical Moisture Sensitivity Level (MSL 1) and support the same 50-position, 2-row configuration with outer shroud contacts. The substitute part is Active in product status with 1148 pieces available in inventory.

Selection between these parts depends on termination method compatibility with the printed circuit board assembly process. Press-fit termination (5557984-2) provides automated insertion capability, while solder termination (B57-050-221-202) integrates with wave or reflow soldering processes.

Frequently Asked Questions (FAQ)

Q: Can B57-050-221-202 be used as a direct replacement for 5557984-2?

A: B57-050-221-202 is functionally equivalent in electrical and mechanical specifications (50 positions, 2 rows, through-hole mounting, outer shroud contacts, gold finish). The primary difference is termination method: B57-050-221-202 uses solder termination while 5557984-2 uses press-fit termination. Substitution is valid only if the application design accommodates solder termination instead of press-fit assembly.

Q: What is the difference between press-fit and solder termination?

A: Press-fit termination uses mechanical insertion of connector contacts into plated through-holes on the PCB, typically performed by automated equipment. Solder termination requires the connector leads to be soldered to PCB pads or through-holes using wave or reflow soldering processes. Both methods provide electrical connection; the choice depends on manufacturing process capability and design requirements.

Q: Are there packaging differences between these parts?

A: Yes. The 5557984-2 is supplied in Bulk packaging, while B57-050-221-202 is supplied in Tray packaging. Packaging does not affect connector performance but may impact receiving, storage, and handling procedures. Tray packaging typically provides better component protection during shipment and storage.

Q: Do both parts meet the same regulatory compliance standards?

A: Both parts are RoHS Compliant (5557984-2 is RoHS Compliant; B57-050-221-202 is ROHS3 Compliant). Both carry REACH Unaffected status. Both maintain MSL 1 (Unlimited) moisture sensitivity rating. Regulatory compliance is equivalent for both parts.

Q: What is the flange feature difference?

A: The 5557984-2 features Housing/Shell (4-40) flange, while B57-050-221-202 features Board Side (4-40) flange. Both support 4-40 mounting hardware. Housing/Shell flange mounts to the connector housing, while Board Side flange mounts directly to the PCB. This difference affects mechanical mounting configuration but not electrical performance.

Q: Can these connectors be used interchangeably in the same PCB design?

A: Interchangeability requires that the PCB design accommodates the specific termination method. If the PCB is designed for press-fit termination with plated through-holes, only 5557984-2 is suitable. If the PCB is designed for solder termination with solder pads, only B57-050-221-202 is suitable. PCB layout and manufacturing process must align with the selected connector termination method.
